Description
Scalar field dark matter models (such as Fuzzy Dark Matter, axion-like particles, ultra-light DM) are interesting dark matter
candidates. Their gravitational dynamics follow the usual CDM behaviours on large scales but differ on small scales because
of wave effects or self-interactions.
I will briefly present two aspects of their gravitational dynamics: the formation of solitons, which could play a role for the
tensions of CDM on galactic scales, and the accretion onto Black Holes, which could provide a probe of such DM clouds
through gravitational waves.
